Donald Trump was born in Pakistan and raised as a Muslim, according to a bizarre theory spreading across the internet.

Thousands of social media users claim the US president-elect was born in lawless North Waziristan in 1946 and named Dawood Ibrahim Kham.

People have even said a photo of a little blonde boy pictured in the country in the early 1950s proves the weird ideology.

Trump - 'aka Kham' - was apparently educated in Madrassa until a car accident killed his parents in 1954.

He was then fostered by a retiring British Indian Army captain, who took him to London, where he was adopted by the Trump family in 1955.

Broadcaster Neo News shared the story alongside several posts on social media, as the host announced: “Believe it or not, presidential candidate Donald Trump was born in Pakistan and not in America.”

If the statement is true it would render Trump, 70, ineligible to be president of the United States as the US Constitution says the nation’s leader has to be a “natural born citizen.”

Trump came under fire during his election campaign after repeatedly saying that President Barack Obama, 55, was not a US citizen even though he was born in Hawaii to a Kenyan dad.

After he continued to call on Obama to show his birth certificate it seems the tables have turned, as thousands of people are saying Trump must do the same. People also want him to take a DNA test.

North Waziristan is a notorious hotbed of Islamist militancy and a haven for groups such as al-Qaida and the Taliban.

The odd theory has spread after Trump and Russian leader Vladimir Putin vowed to tackle terror group ISIS this week.

Less than a week after the billionaire’s election, the Kremlin said Putin called Trump yesterday to begin negotiations over how best to tackle to terrorism.

The Russian is reported to have said he is ready for dialogue with the US “on the basis of mutual respect, non-intervention into each other’s internal affairs”.

According to the news agency Kremlin, Putin and Trump have agreed to “work to channel bilateral relationships into constructive cooperation, to combine efforts to tackle international terrorism and extremism, and to continue contact by telephone and to work towards meeting in person”.
